Earlier in the day, protesters from the so-called End The Drone Wars group released a statement explaining their intention to come to the RAF Waddington airfield and protest.
The protesters also hung banners on the perimeter fence of RAF Waddington, calling to stop launch and use of unmanned aerial vehicles (UAV) from the air base and pointing out civilian casualties caused by the use of drones during the wars in Afghanistan and Iraq.
Two men and two women involved in the protests were detained by the Lincolnshire Police after they attempted to cut through the RAF Waddington fence, the Lincolnite website reported Monday.
The End The Drone Wars also confirmed both their detention and subsequent arrest on their Facebook page.
Still waiting to hear from activists in Lincoln police station, possible charges are aggravated trespass and criminal damage.

The RAF Waddington is the main operating base for what it terms "airborne intelligence systems," according to its official website. From this base the RAF remotely controls Reaper aircraft, which have been actively used in Iraq and Afghanistan by British forces.
The Monday protest is the most recent in a series of protests directed against the RAF's involvement in UAV use during military operations abroad.
